This invention relates to a machine designed for use in feeding, delivering or discharging an extremely variable amount of pulverized, semicoarse or whole-grain materials. V

A primary object'of the invention is to provide a machine of this character which may be adjusted to various settings, depending on the amount of material to-be delivered, the adjustment being such as to allow'a great number of settings; betweent'he minimum and maximum of the feeding capacity of the machine.

Still another object "of the invention is to provide a'machine of this character which will cause the material under treatment, to be formed into a layer on the'rotating cone or disk, there being provided adjustable slides adapted 'to contact with the material, spreading-the material over the cone ordisk' in layers of'various degrees of thickness.

With the foregoing and other objects in view which will appear as the description'proceeds, the

invention consists'of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts withoutdeparting from the spirit of the invention as claimed.

Referring to the drawings Fig. 1 is a front elevational view of a percentage feeding machine, constructed in accordance with the invention.

2 is a vertical sectional view through the machine.

Fig. 3 is a plan view of the machine.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 2.

Referring to the drawings in detail, the reference character 5 designates the base of the machine from which the supporting plates 6 rise, the supporting plates 6 being held in spaced relation with respect to each other, by means of the horizontal plate I, which is shown as having its ends connected to the plates 5. This horizontal plate 7 provides a bearing for the vertical shaft 8 which extends into the body portion of the machine, as clearly shown by Fig. 2 of the drawings.

The power shaft of the machine is indicated by the reference character 9 and is provided with a pinion I0 that meshes with pinion ll secured to the lower end of the shaft 8, whereby rotary movement of the shaft 9 is transmitted to the shaft 8.

Mounted on one end of the shaft 9, is a pulley I2 over which a belt not shown, and which operof the feed disk [5,

operate, to rotatethe shaft 9.

The body portion of the'machine is indicated generally'by the reference character l3, and in cludes a bottom' [4, which is hollowedoutslightly,

sothat material passingonto the: bottom, will be retained in the hollowed out'portion.

Secured on the upper end of -the shaft is the delivery disl: I5, which is curved downwardly from the center thereof,' the periphery of the disk beingspaced slightlyfrom the inner surface of the body l3, so that materialunder treatment will wedged-"or fpacl te'd between the disk notfbe'come r e and wall of the bodyfl3.

The connection between the partitions [8 and l9, forms a vertical guideway in which one edge of the vertical partition 2!) slides, the opposite edge of the vertical partition 20 moving in the guide 2| which is secured to the inner surface of the body 13. Rack bars 2| are secured to the surface of the vertical partition 20, adjacent to the opposite side edges thereof, which rack bars cooperate with the pinions 22, carried on the shaft 23 that is mounted in bearings 24 mounted on the top 25 of the body portion. A handle 26 is formed on one end of the shaft 23, whereby the shaft 23 may be rotated to adjust the vertical partition 20, so that the lower edge thereof may be moved to various positions,

v' 'rtical blades: I s rail-antennas from-the thereof, is cutproviding ad schargeopening awn, so that he reference, manage-it designates a para partition 20, or partially close the same as desired, to insure a predetermined quantity of material to receive the threaded shank 29, which extends through an opening inthe inturned end 30 of the partition 20, the shank 29 being provided with a hand-wheel 3|, whereby the adjustmentof the, slide valve 28 may be made readily.

The reference character 31*" designatesa horizontal shaft that extends through the body of the 7 machine, the shaft 3| being provided with fingers 32. thatextend laterally therefrom, and which fingers operate to agitate material in. the body to prevent, the material from packing.

A pu1ley 33is mountedon. one end or the. shaft 3 l1", andlreceives motionfrom-theemainz shaft 9 of the machine, throughthe belt 34, which operates over the pulley 33,, and. pulley 35-, secured to one end: of the shaft, 9.

Mounted at the: front of the machine, directlyunder the: discharge opening oi; the body portion, is a delivery hopper 36 from whichlthespouts 31 3.3 extend, thererbeing, provided a valve'member 39 within the hopper, which maybe moved to direct material from the hopper toeither spout. 33 or 3d,, to, facilitate. the delivery of. the material to bags or-receptaelesbeing filled with the mate-- ll'iarl'.v V 1 V In the operation at the. machine, material is fed into the body portiom where, it falls onto, the

7 ,feed disk The feed disk. being constantly rotated, discharges, the, material, due to centrifugal: force; into the hopper. 36. Where it is carried.

through: the; spent, 31- 012-38. toa place. of deposit.

By adjusting the vertical partition 20. and the slide valve 2%,, thethickness ot the, material carried throughthe open sideof, the. hopper, may be regulated; to the end that a. predetermined pera certain materiak 01 amix, may be.

centageof a insured.

What is claimed is:

1; In a device of the class described, a body portion having a discharge opening in the wall thereof, a partition within the body portion dividing the body portion into a receiving compartment and a feed compartment, said partition having an opening through which material passes from the receiving compartment to the feed compartment, a Vertically movable main valve member mounted on the partition and, adapted to move over the; opening of the: partition,, regulating the quantity of material fed through the feed compartment, said main Valve member having an opening through which material passes, a second slide valve mounted on the main valve member and being movable over the opening of the main valve member regulating the quantity of material delivered to the. feed compartment, and a rotary feed disk operating in the body portion and adapted to deliver material from the feed compartment.

2. In a device ofthe classdesnribed;v a body-portion. having: a; discharge; opening: initthe wallthereof, a rotary disk, operating at the bottom of the body portion and: on to which; materiak is iedg, a

substantially widev vertically movable; partition,

dividing the; body portion into a receiving compartment-and adelivery compartment, the lower edge or? they vertically movable partition. being; spaced from: the? surfacehofr the; disk, whereby material may pass under'the partition, means for moving; thepartition vertically,v regulating the space between the lower-edge: of the; partition, and: disk, said partition having: an opening disposed: intermediate its: side-edges and: extending upwardlyfrom the lower edge thereoii, a substantial-lynarrow slide valve member mountedon-thepartitionand adapted tov move; over-saidi opening,- regulating the size of said opening, means for moving the slide valve member with respect to the partition wherebythe: quantity of material transferred. from. the receiving; compartment to the delivery compartment may be: regulated, and said;
